Abstract
A study on the seafood consumption was conducted from 1902 adolescent students (1110 boys and 792 girls) attending middle or high school to assess the attitude and degree of satisfaction for seafood being served in the school lunch program and ultimately to promote greater seafood consumption. A self-administered questionnaire was used to record the results. The results were as follows: Sixty percent of the respondents appeared to like or not to be reluctant to seafood. The main reasons for favoring seafood were its nutritious effect and taste. On the other hand, the reason for disliking seafood was due to its peculiar smell. In terms of cooking methods, the subjects preferred raw, fried, and grilled seafood, whereas they disliked salt-fermented, seasoned and stewed dishes. The highly preferred seafoods were crab, shrimp, tuna and squid. Only 6.6% of middle school students (MS) and 3.7% of high school students (HS) liked the seafood served in school lunch program, whereas the others responded ‘so so’or disliked it. The reasons for disliking seafood being served in school lunch program were poor taste (14.7% of MS, 23.5% of HS), lack of freshness(6.3% of MS, 13.9% of HS) and unattractable cooking methods(3.4% of MS, 11.1% of HS). To promote seafood consumption in school lunch program, the subjects anticipated the taste improvement (37.7% of MS, 48.5% of HS), use of a variety of seafood (19.8% of MS, 24.0% of HS) and cooking methods(12.6% of MS, 22.4% of HS). Above results suggested that further efforts are needed to provide preferred cooking methods and seafood items as a way of increasing seafood acceptability.

Abstract
The nitrite scavenging effect of three kinds of edible wild plants belong to Umbelliferaeceae family was investigated. The contents of crude protein, crude lipid and β-carotene of the plants were in the range of 22.99∼31.00%, 3.51∼5.08% and 5.40∼19.81 ㎎%, respectively. The content of ascorbic acid was very low and selenium was not detected in any samples. The contents of linoleic acid and linolenic acid were 66.46∼77.44%. The content of total phenol was 875.77 ㎎% in Ledebouriella seseloides WOLFF, which was the highest among the samples. The methanol fraction of the plant extract showed higher nitrite scavenging effect than the water fraction. The nitrite scavenging effects of the samples were the highest at pH 1.2 and lowest at pH 6.0, suggesting that it`s pH dependent. Nitrite scavenging effect of methnol-soluble fractions obtained from Ledebouriella seseloides WOLFF was 95.3% at pH 1.2, which was the greatest among tested samples. There was a high correlation between the nitrite scavenging effect and the total phenol content.

Abstract
The quality of an angel food cake prepared with albumen of irradiated eggs was investigated. Fresh shell eggs were irradiated at various doses up to 3 kGy. Egg white from irradiated eggs decreased the specific gravity and increased the pH of cake batter. The specific volume and expansion ratio of the cake increased by the use of albumen from irradiated eggs. Egg white from irradiated eggs made the crust color of cake darker, more reddish and yellowish. The textural characteristics of the cake were also affected by irradiation. Irradiation caused a decrease in hardness, gumminess and brittleness and an increase in cohesiveness and springiness. Overall, egg white from irradiated eggs apeared to make an angel food cake softer than that of non-irradiated egg white.

Abstract
The purpose of this study was to develop a seasoned Hwangseoke-jeot(a kind of salted and fermented fish) with chitosan having less fishy smell and salty taste. In order to decrease the fishy smell and increase the palatable taste effectively, four types of seasoning were developed, in which minced ginger, garlic and onion were included. In order to improve the color and flavor of seasoned Hwangseoke-jeot, high-quality powdered hot red pepper was also added in all the seasonings. Seasoned Hwangseoke-jeot type 1 had the oil and roasted powder of sesame, which are known to decrease fishy smell and palatable taste, and was the basis of other seasoned Hwangseoke-jeot. Type 2 had the oil and roasted powder of perilla, which also were known to decrease fishy smell and to increase palatable taste effectively. Type 3 had roasted soybean powder and laver to increase savory and palatable taste. It was developed especially for old and young people who like savory taste. Type 4, containing citron syrup, was for the young and children. All the developed seasoned Hwangseoke-jeot samples had better red color and other sensory properties than the control (S-company`s seasoned Hwangseoke-jeot), as tested by colorimetry and sensory evaluation. More than 1% (w/v) of chitosan gave an astringent taste to seasoning, so it is recommended not to exceed 1% (w/v) in the seasoning. The developed functional seasonings of jeot would be applicable to other kinds of jeot.

Abstract
This study was carried out to develop a traditional functional beverage by using hot-water extraction of dried peels of Korean tangerine. The pH of the hot-water extracts of dried tangerine peels decreased as the extraction time increased. The acidity and viscosity of the extracts increased as the extraction time increased. The antioxidative activity of the extracts during the extraction was monitored by measuring the electron donating ability. The electron donating abilities of the extracts were in the range of 80.93-83.27%. Extraction time did not affect the antioxidative activity of the extracts. The fibrinolytic activity of the extracts increased as the extraction time increased. The pH of the beverage made with the peel extract was not affected by the extraction time and the kind of sweetener added. The viscosity of the beverage increased as the extraction time increased. In sensory evaluation, the highest score was obtained in the beverage samples made with the ones extracted for 180 min and added with sugar. The above results indicate that the dried peel of Korean tangerine can be used as a functional material in beverage industry.

Abstract
The effect of sodium metabisulfite and adipic acid on the color changes of garlic juice was evaluated. The garlic(Uisung variety) juice was extracted and 1% sodium metabisulfite and 1% adipic acid were added to the garlic juice before or after concentration. Garlic juice was concentrated by heating at 90℃, by heating using a rotary vacuum evaporator at 45℃, or by freeze-drying at -50℃ until the volume was reduced to 70% of the original volume. The garlic juice concentrate was kept at 4℃ and 25℃ for 60 days and evaluated for the color change and the relation between the additives and browning. Browning of the garlic juice concentrate containing adipic acid and sodium metabisulfite was effectively inhibited compared with the control. Inhibition effect of sodium metabisulfite on the browning of the concentrate was stronger than that of adipic acid. The addition of sodium metabisulfite after concentration of garlic juice was the most effective on browning inhibition in the 90℃-heated concentrate, but the addition of sodium metabisulfite before concentration was the most effective in the 45℃-heated concentrate and the -50℃-freeze-dried concentrate. In the color change of the garlic juice concentrate during the storage, a and b values of the concentrate with sodium metabisulfite were lower than those of the control, which means that sodium metabisulfite inhibited the browning of the garlic juice concentrate.

Abstract
Effect of copper ions (Cu^+ and Cu^2+) on the fermentation of kimchi, especially on their effect on the prevention of over-acidification of kimchi, was investigated. The effect of Cu^2+ ion on the growth of individual lactic acid bacterium originally isolated from kimchi was also investigated. The addition of Cu^+(≥4.0mM) or Cu^2+(≥3.0mM) ions in kimchi effectively inhibited growth of lactic acid bacteria and maintained a titratable acidity of less than 1.0% for a periods of 14 days. Leuconostoc mesenteroides significantly decreased at the 10th day of fermentation in control kimchi, whereas the group with Cu^+ and Cu^2+ showed 10^5-10^6 CFU/㎖ at the 14th day of fermentation. This indicates that the addition of Cu^+ and Cu^2+ inhibited the production of excessive acids by inhibiting lactic acid bacteria, and allowed Leu. mesenteroides stay alive longer. Fe^2+ and SO_4^2- ions did not have any effect on the fermentation of kimchi. Cu^2+ inhibited growth of all lactic acid bacteria tested, such as Leu. mesenteroides 6, Streptococcus faecalis 12, Lactobacillus plantarum 14, Lac. brevis 15, Leu. mesenteroides LA 10, and Lac. plantarum LA 97.

Abstract
The dietary carbohydrates are mainly digested and adsorbed at small intestine. We developed a new food additive as an egg yolk antibody(IgY) against maltase, sucrase and sodium dependent glucose cotransporter(SGLT) for the regulation of blood glucose level and weight control. The maltase, sucrase and SGLT were purified from porcine small intestine which is very similar to that of human in physiological characteristics. The purification step contained an ultracentrifugation, ion exchange chromatography and hydrophobic chromatography. The hens were immunized by purified protein and the IgY activities against immunized antigens were determined. This antibody obtained from the immunized hen`s egg yolks directly inhibited the activities of maltase and sucrase in vitro. And the IgY delayed and decreased the increment of blood glucose level after administration of maltose, sucrose and glucose in rat about 30 to 60%. The results of this study suggest that the IgY inhibiting the carbohydrate digestion could be used as functional food materials for weight control and regulation of blood glucose level in diabetes.

Changes in Chromaticity and 6 Mineral Contents of Sea Mustards according to Several Cooking Methods 조리에 따른 미역중의 색도 및 무기성분의 변화
This study aimed to determine the effects of cooking treatment on chromaticity and 6 mineral contents (calcium, phosphorus, magnesium, iron, sodium and potassium) in sea mustards. Four samples of natural and cultured sea mustard were used for the experiments. Each sample was treated with four cooking methods (A: soaked in water, B: boiled in hot water, C: saute^ and boiled in hot water, D: seasoned with vinegar). The L, a and b values were the highest on boiling, and the lowest on seasoning with vinegar. The a value of cultured sea mustard was higher than the natural one by cooking. Moisture was highest boiling and were ordered as saute^ and boiling, soaking and seasoning with vinegar. Calcium, iron, magnesium and phosphorus contents were remarkably decreased by seasoning with vinegar. Boiling treatment made less decrease than saute^ and boiling in these mineral contents. The solubilities of mineral in soup water were recognized therefore, it indicated that soup water was a good source of minerals as it applies to cooking, from the view point of science of cookery. Sodium and potassium contents decreased significantly more at 68% and 85% of total content on basic soaking treatment. Ca/P ratio was about 1∼3 : 1 in cultured sea mustard and 3∼4 : 1 levels in natural one.

Abstract
This study was intended to investigate the breakfast habits of salaried people. Total 446 subjects (male:256 and female:190) living in Seoul participated in the study. The results obtained were as follows : About 88.8% of the respondents perceived well the importance of breakfast, but only 33.2% of them responded to have breakfast every morning. It was found that males, older people, married people and people with higher education had a tendency to have breakfast regularly. The main reasons for having breakfast were ’for nutritional intake ’(42.2%) and ’for relieving hunger’(31.3%). Cooked rice with soup (78.4%) was the most popular menu for breakfast. The time for breakfast was about 5∼15 minutes. The reasons for skipping breakfast were ’the lack of time > low appetite > habitually’, but 59.6% of the respondents answered to have cooked rice with soup if they would. The 95.6% of the respondents showed more than the ’moderate’score on nutritional knowledge. Female salaried people showed higher scores on nutritional knowledge than male counterparts. People with higher education had a better nutritional knowledge. It was found that male, older people, people with higher education, and members in the extended family or nuclear family had good eating habits. Nutritial knowledge showed a significant positive relationship with eating habits. Overall, salaried people perceived the importance of breakfast, but had poor dietary habit of skipping breakfast at 23.3%. Therefore, convenient and nutritional substitute for breakfast should be developed for salaried people.
